[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0038] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component present.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0040] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0042] In existing folding cabinets, the connecting components typically only have a single function of fixing or rotating. This requires the use of various connecting components with different structures and functions to complete the overall assembly of the folding cabinet, resulting in redundant overall structure, a large number of parts, and cumbersome assembly procedures. Furthermore, the dispersed structure may cause the folding cabinet to loosen after repeated folding and use, resulting in poor overall structural stability, affecting its service life and user experience.
[0043] To solve the above problems, such as Figures 1 to 19 As shown, this utility model provides a connector, a folding frame, and a folding cabinet. The connector integrates multiple functions to reduce the number of parts in the folding cabinet.
[0044] like Figures 1 to 3 As shown, the height of the folding cabinet is defined as the Z-axis, the depth as the X-axis, and the width as the Y-axis. The height, depth, and width directions are all perpendicular to each other. For ease of description, the following example uses +Z as the top, -Z as the bottom, Y as the left and right, +X as the front, and -X as the back. However, in actual use, users can adjust the placement of the folding cabinet according to their needs; no specific restrictions are imposed here.
[0045] like Figures 1 to 5 As shown, specifically, the folding cabinet includes a folding unit 10, which comprises two square support structures, four folding components 3, and two back panels 4. Specifically, the two square support structures are stacked along the height direction of the folding cabinet; the four folding components 3 are respectively located at the four corners of the support structures, each folding component 3 including two folding pieces 31 arranged sequentially along the height direction, with one end of each folding piece 31 rotatably connected to the other, and the other end of each folding piece 31 rotatably connected to the two support structures respectively. The rotation axis between the two folding pieces 31 and the rotation axis between the folding pieces 31 and the support structures are parallel to the width direction of the folding cabinet; the two back panels 4 are located on the rear side of the folding unit 10, arranged sequentially along the height direction and corresponding to the two folding pieces 31 of the folding components 3, with each back panel 4 connected to the corresponding folding piece 31 on both sides along the width direction. This folding cabinet can be a wardrobe, shoe cabinet, storage cabinet, or other cabinet that requires folding, handling, and storage; this embodiment of the invention does not impose specific limitations.
[0046] In the folding cabinet provided by this utility model embodiment, in the unfolded state, the two folding pieces 31 of each folding component 3 rotate to be parallel to the Z-axis, so that the two supporting structures and the four folding components 3 can form a stable frame structure, which can be used to store clothing, shoes and other items. When folding is required, the four folding components 3 are folded, so that the two folding pieces 31 of each folding component 3 rotate, and each folding piece 31 rotates relative to the supporting structure. At the same time, the back panel 4 moves synchronously with the folding pieces 31, so that the two supporting structures move closer to each other. The entire folding cabinet folds efficiently in the Z-axis direction. After folding, the structure is compact and occupies little space, which is convenient for handling and storage. Moreover, no parts need to be disassembled, which can ensure the integrity and consistency of the folding cabinet. When unfolding is required, the upper supporting structure is lifted, so that the entire folding cabinet is off the ground. Under the action of gravity, the two supporting structures will separate from each other, and each folding piece 31 rotates to be parallel to the Z-axis and supported between the upper and lower supporting structures, thus stabilizing the folding cabinet in the unfolded state. The folding and unfolding steps of this folding cabinet are simple and convenient, and easy for users to operate.
[0047] It should be noted that the square support structure can be either rectangular or square.
[0048] like Figures 1 to 3 As shown, the folding cabinet includes at least two folding units 10 arranged sequentially along the height direction of the cabinet, with two adjacent folding units 10 sharing a common support structure. This increases the overall storage capacity of the folding cabinet. The fact that two adjacent folding units 10 share a common support structure further reduces the overall thickness of the folding cabinet, decreases the number of parts, and minimizes the thickness of the cabinet in its folded state, achieving more efficient space compression for easier handling and storage.
[0049] like Figures 1 to 3 As shown, the folding cabinet includes at least two folding units 10 arranged sequentially along its width. Two adjacent folding units 10 share two folding components 3 located on the front and rear sides. This increases the overall storage capacity of the folding cabinet. The sharing of folding components 3 between two adjacent folding units 10 improves the cabinet's integrity and consistency, ensuring that multiple folding unit groups can be unfolded or folded simultaneously. It also reduces the overall width of the cabinet and the number of parts, facilitating handling and storage. Users can choose the arrangement of the folding units 10 according to their actual needs, giving the folding cabinet good modularity, facilitating production, assembly, and expansion, and adapting to different size and functional requirements.
[0050] In the illustrated embodiment, the folding cabinet includes five folding units 10 along the height direction and three folding units along the width direction, forming a 5×3 folding cabinet. Of course, in other embodiments, the number of folding units 10 along the height direction can be one, two, three, four, six, or more, and the number of folding units 10 in each group along the width direction can be one, two, four, five, six, or more. The specific number can be adjusted according to actual storage needs, and this embodiment of the present invention does not impose specific limitations.
[0051] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the supporting structure includes a shelf 1 and a frame 2 surrounding the shelf 1, with the shelf 1 and frame 2 detachably connected. The frame 2 connects each folding unit 10, ensuring the overall stability of the folding cabinet. The shelf 1 holds items such as clothing and shoes and divides the folding cabinet into sections for user convenience. The detachable shelf 1 allows users to choose whether to install it as needed. For example, when the volume of an item exceeds the capacity of one folding unit 10, the shelf 1 can be removed, allowing two or more folding units 10 to form a single space, thus expanding the applicability of the folding cabinet. Furthermore, the detachable connection between the shelf 1 and frame 2 improves the modularity of the folding cabinet, facilitating cleaning, maintenance, or replacement of individual components, extending the overall lifespan of the folding cabinet. It also facilitates disassembly, packaging, and transportation of the shelf 1 and frame 2, reducing space occupation and transportation costs. Of course, in other embodiments, the shelf 1 and frame 2 can also be a single unit, such as integrally molded, or fixedly connected by adhesives, fasteners, or other means.
[0052] like Figures 5 to 12 As shown, in one embodiment, the frame 2 includes four crossbeams 21 and four connectors 22. The four crossbeams 21 form a square structure, and the four connectors 22 are respectively located at the four corners of the square structure and are detachably connected to two adjacent crossbeams 21. Two square frames 2 and four folding components 3 form a folding frame. The frame 2 is assembled from the crossbeams 21 and connectors 22, resulting in fewer types of parts, further improving the modularity of the folding cabinet, reducing manufacturing and maintenance costs, and facilitating disassembly, packaging, and transportation of the crossbeams 21 and connectors 22, reducing space occupation and transportation costs. The support structure of two adjacent folding units 10 along the width direction can share one crossbeam 21 and two connectors 22 to improve the overall integrity and consistency of the folding cabinet and reduce the number of parts. Of course, in other embodiments, the frame 2 can also be a single unit, such as integrally molded, or the parts can be fixedly connected by adhesives, fasteners, etc. Figure 4 Taking the folding unit 10 as an example, Figure 9For the left crossbeam 21, Figure 10 For the right-side crossbeam 21, Figure 11 For the rear crossbeam 21, Figure 12 The front crossbeam is 21.
[0053] It should be noted that when the square structure is a square, the four crossbeams 21 have the same length; when the square structure is a rectangle, the two opposite crossbeams 21 have the same length, while the lengths of two adjacent crossbeams 21 can be different. Furthermore, along the width direction of the folding cabinet, different folding units 10 can use front and rear crossbeams 21 of different lengths.
[0054] like Figure 6 As shown, the connector 22 includes a connecting portion 221, a first mounting portion 222, a second mounting portion 223, and a first rotating portion 224. The connecting portion 221 includes a first side surface 2211, a second side surface 2212, and a third side surface 2213 that are perpendicular to each other and adjacent to each other. The first mounting portion 222 is located on the first side surface 2211 and is used to connect the crossbeam 21 of the folding cabinet. The second mounting portion 223 is located on the second side surface 2212 and is used to connect the crossbeam 21 of the folding cabinet. The first rotating portion 224 is located on the third side surface 2213 and is used to rotatably connect with the folding components 31 of the folding cabinet. Specifically, the first mounting portion 222 and the second mounting portion 223 of the connector 22 are detachably connected to two adjacent crossbeams 21, and the ends of the two folding components 31 furthest from their rotatably connected ends are rotatably connected to the first rotating portion 224.
[0055] In the connector 22 provided in this embodiment of the utility model, by integrating a first mounting part 222, a second mounting part 223, and a first rotating part 224 on the connecting part 221, the connector 22 simultaneously possesses multiple functions, including connecting the crossbeams 21 in two directions and rotating with the folding part 31, thereby reducing the number of parts. This connector 22 can serve as a standard part, making it suitable for frames 2 of different sizes and shapes, thus improving production efficiency and part interchangeability, enhancing production efficiency and convenience, and reducing costs. Furthermore, the mutually perpendicular and adjacent first side 2211, second side 2212, and third side 2213 on the connecting part 221 constitute a stable mechanical structure, ensuring the stability and reliability of the connector 22 itself and the assembled folding cabinet, preventing loosening after prolonged use, thereby improving the overall integrity, stability, and reliability of the folding cabinet, extending its service life, and enhancing the user experience.
[0056] like Figure 6 and Figure 15As shown, in one embodiment, the first rotating part 224 is provided with a first shaft hole 2242, and the end of the folding member 31 connected to the first rotating part 224 is provided with a second shaft hole 312. The first rotating part 224 and the folding member 31 are rotatably connected at the first shaft hole 2242 and the second shaft hole 312 through a first rotating shaft (not shown). This effectively prevents the folding member 31 from shaking or jamming during rotation, ensuring the stability of the folding cabinet during folding and unfolding. It also prevents the folding member 31 from sliding along its width, improving the overall strength and stability of the folding cabinet. Of course, in other embodiments, one of the first rotating part 224 and the folding member 31 may be provided with a shaft hole, and the other with a rotating shaft; or, the first rotating part 224 and the folding member 31 may be connected by a hinge, other structures, or any other means that allow for rotatable connection. This embodiment of the present invention does not impose specific limitations.
[0057] like Figure 6 and Figure 15 As shown, the first rotating part 224 includes a first engaging part 2241 for detachably engaging with the folding component 31. Specifically, the end of the folding component 31 connected to the first rotating part 224 is provided with a first slot 313 that can engage with the first engaging part 2241. In the unfolded state, the first engaging part 2241 engages with the first slot 313 to ensure the stability and reliability of the folding assembly 3 in the unfolded state, prevent the folding component 31 from accidentally rotating and folding relative to the connecting member 22, and reduce shaking of the folding cabinet during use. In the folded state, the first engaging part 2241 separates from the first slot 313 to avoid affecting the normal rotation of the folding component 31. Furthermore, the assembly and disassembly of the first engaging part 2241 and the first slot 313 are simple and easy for users to operate.
[0058] like Figure 5 As shown, the connector 22 also includes a first limiting portion 225 provided on the third side 2213. The first limiting portion 225 is used to contact the folding member 31 when the first engaging portion 2241 engages with the folding member 31. Contact between the first limiting portion 225 and the folding member 31 means that they may abut each other, or there may be no interaction force. Thus, when the first limiting portion 225 contacts the folding member 31, it can restrict the folding member 31 from continuing to rotate relative to the connector 22 toward the first limiting portion 225, thereby providing a clear limit and guide for the rotation of the folding member 31. Furthermore, when the first limiting portion 225 abuts against the folding member 31, it can also improve the stability of the folding member 31 in the unfolded state and reduce the possibility of accidental folding of the folding member 31.
[0059] like Figure 5As shown, in one embodiment, the first mounting part 222 and the second mounting part 223 are second insertion parts for detachably engaging with the crossbeam 21. Specifically, both ends of the crossbeam 21 are provided with second slots 2111 that can engage with the second insertion parts. Thus, the connection between the crossbeam 21 and the connector 22 is simple, allowing for quick assembly and disassembly without the need for external tools, facilitating user operation and improving the usability and convenience of the folding cabinet. Of course, in other embodiments, the crossbeam 21 and the connector 22 can also be detachably connected through snap-fit, interference fit, or detachable screws, bolts, or other fasteners, as long as the stability and reliability of both in the assembled state can be ensured. This embodiment of the present invention does not impose specific limitations here.
[0060] like Figure 6 As shown, when two adjacent folding units 10 along the height direction share the connector 22, the connector 221 includes two opposing third side surfaces 2213, and two first rotating parts 224 are respectively disposed on the two third side surfaces 2213. The two first rotating parts 224 are used to connect the upper and lower folding parts 31 respectively. In this way, the versatility and standardization of the connector 22 can be improved, the number of molds and production costs can be reduced, and the production and assembly process can be simplified.
[0061] like Figure 7 As shown, when two adjacent folding units 10 along the width direction share the connector 22, the connector 221 includes two opposing second side surfaces 2212, and two second mounting parts 223 are respectively provided on the two second side surfaces 2212. The two second mounting parts 223 are used to connect the crossbeams 21 on the left and right sides, respectively. In this way, the versatility and standardization of the connector 22 can be improved, the number of molds and production costs can be reduced, and the production and assembly process can be simplified.
[0062] like Figures 1 to 3 As shown, furthermore, when the supporting structure is located on the upper and lower sides of the folding cabinet as a whole, the supporting structure may also include end plates 6. End plates 6 can be positioned above or below the original frame 2 and shelf 1; alternatively, end plates 6 can replace at least one of the frame 2 and shelf 1. This further improves the overall aesthetics and stability of the folding cabinet.
[0063] like Figure 8As shown, the connecting part 221 also includes a fourth side 2214 arranged opposite to the first side 2211, and the connecting member 22 also includes a third mounting part 227 disposed on the fourth side 2214. The third mounting part 227 is used to connect the door of the folding cabinet (not shown in the figure). The door is arranged opposite to the back panel 4, which can close the front of the folding cabinet, improve the overall aesthetics of the folding cabinet, and effectively prevent dust and moisture, protect the items inside the folding cabinet, and expand the application range of the folding cabinet. In this embodiment, each folding unit 10 can correspond to one door, or two, three or more folding units 10 can share one door. The specific configuration can be adjusted according to actual needs, and this embodiment of the present invention does not impose specific limitations. The third mounting part 227 serves as the hub connecting the frame and the door, realizing that the crossbeam 21, folding member 31 and door and other components are all centrally installed on the connecting member 22, improving the integrity and assembly convenience of the folding cabinet. Furthermore, the door body is detachably connected to the third mounting part 227. When folding is required, the door body can be disassembled first, and the user can also choose whether to install the door body according to actual needs.
[0064] like Figures 9 to 12 As shown, in one embodiment, the crossbeam 21 includes a connecting section 211 and a support section 212 located inside the connecting section 211. The connecting section 211 is detachably connected to the connector 22. The shelf 1 is mounted on the support section 212 and is detachably snapped into it. The support section 212 supports the shelf 1 from below, improving its stability and reliability and distributing its load. The connecting section 211 is located outside the support section 212, ensuring a reliable connection between the crossbeam 21 and the connector 22 while preventing the shelf 1 from sliding relative to the frame 2, thus avoiding tilting or falling. Furthermore, the connection between the shelf 1 and the crossbeam 21 is simple, allowing for quick assembly and disassembly without external tools, facilitating user operation and improving the usability and convenience of the folding cabinet.
[0065] Of course, in other embodiments, the shelf 1 may be mounted on the support section 212 and detachably connected to the connecting section 211; the crossbeam 21 may only include the interconnected support sections 212, the shelf 1 may be mounted on the support section 212 and detachably connected to the support section 212; or, the crossbeam 21 may only include the interconnected connecting sections 211, the outer periphery of the shelf 1 may be detachably connected to the connecting section 211.
[0066] like Figures 9 to 12 and Figure 19As shown, specifically, the support surface of the support section 212 is provided with a second slot 2121, and the shelf 1 is provided with a third engaging part 11 that can engage with the second slot 2121. The connection structure between the shelf 1 and the support section 212 is simple, and in the engaging state, it can ensure that the crossbeams 21 and the connectors 22 will not detach from each other, improving the reliability of the connection between the shelf 1 and the frame 2, thereby improving the stability of the support structure and preventing the support structure from shaking or producing abnormal noise during use. The number of second slots 2121 on each support section 212 can be one, two, three, or more, and the multiple second slots 2121 are arranged at intervals along the length of the support section 212. The third engaging part 11 is arranged in a one-to-one correspondence with the second slots 2121 to ensure the stability and reliability of the connection between the shelf 1 and the frame 2.
[0067] like Figure 4 As shown, in one embodiment, the folding unit 10 further includes at least one side plate 5. The side plate 5 is disposed on one side of the folding unit 10 along the width direction. The side plate 5 is rotatably connected to one of the support structures and detachably snapped into another support structure. The axis of rotation between the side plate 5 and the support structure is parallel to the depth direction of the folding cabinet. In the unfolded state, the side plate 5 closes the left and right sides of the folding unit 10, preventing items inside the folding unit 10 from falling from the sides. The snap-fit engagement between the side plate 5 and one of the support structures prevents the side plate 5 from accidentally rotating and folding relative to the support structure, ensuring the stability and reliability of the side plate 5 in the unfolded state. Furthermore, the side plate 5 can also support the upper and lower support structures and the four folding components 3, preventing the folding components 31 from rotating relative to the support structures, thereby enhancing the strength of the folding unit and making the folding cabinet more stable and aesthetically pleasing. When folding is required, the interlocking side plates 5 and support structures are first separated, and the side plate 5 is controlled to rotate to a position where it overlaps with the support structure, so that the side plate 5 does not interfere with the rotation of the folding components 31. Then, the folding components 3 are controlled to rotate relative to the support structure to the folded state. Thus, the side panel 5 does not need to be disassembled during folding, reducing the number of parts and facilitating transportation and storage. Two adjacent folding units 10 along the width direction can share a single side panel 5 to improve the overall integrity and consistency of the folding cabinet, reduce the number of parts, and allow the side panel 5 to rotate toward either folding unit 10 during folding.
[0068] Of course, in other embodiments, the four sides of the side panel 5 can also be detachably connected to two support structures and two folding components 3 respectively. When folding is required, the side panel 5 is first removed, and then the folding components 3 are controlled to rotate relative to the support structures to the folded state. Furthermore, users can choose whether to install the side panel 5 as needed. For example, when the volume of the item is larger than the volume of one folding unit 10, the side panel 5 can be removed, so that two or more folding units 10 form a whole space, thereby expanding the applicability of the folding cabinet.
[0069] like Figure 1 and Figure 4 As shown, in one embodiment, the side panel 5 is rotatably connected to the bottom support structure and can be rotated to be stacked with the support structure. The rotation axis of the folding member 31 and the support structure is higher than the rotation axis of the side panel 5 and the support structure. Thus, after folding, the side panel 5 can be mounted on the support structure, ensuring that the side panel 5 does not interfere with the rotation of the folding member 31, and reducing the space occupied by the side panel 5 in the folded state, making the overall shape of the folding cabinet more compact and regular, facilitating handling and storage. Furthermore, the top of the support structure is provided with a receiving groove, which can be formed by the shelf 1 and the frame 2. In the folded state, the side panel 5 is accommodated in the receiving groove, so that the side panel 5 does not protrude excessively from the support structure in the folded state, further reducing the overall thickness of the folding cabinet in the folded state. Of course, in other embodiments, the side panel 5 can also be rotatably connected to the top support structure.
[0070] like Figure 6 and Figure 18 As shown, specifically, the side panel 5 is rotatably connected to the connecting member 22 of the supporting structure. The connecting member 22 also includes a second rotating part 226 disposed on the first side surface 2211. The second rotating part 226 is used to rotatably connect with the side panel 5 of the folding cabinet. The second rotating part 226 can be a shaft hole, with second rotating shafts 52 on both sides of the side panel 5 capable of rotatably engaging with the shaft holes; or, the second rotating part 226 can be a second rotating shaft 52, with shaft holes on both sides of the side panel 5 capable of rotatably engaging with the shaft holes.
[0071] like Figure 9 and Figure 18As shown, in one embodiment, the side panel 5, which is detachably connected to the support structure, is provided with a third latching part 51, and the connecting section 211 is provided with a third latching groove 2112 that can engage with the third latching part 51. In the unfolded state, the third latching part 51 and the third latching groove 2112 engage; in the folded state, the third latching part 51 and the third latching groove 2112 separate. The engagement of the third latching part 51 and the third latching groove 2112 improves the stability and reliability of the side panel 5 in the unfolded state, prevents accidental folding of the side panel 5, and reduces shaking during use of the folding cabinet. Separation of the third latching part 51 and the third latching groove 2112 does not affect the normal rotation of the side panel 5. Furthermore, the assembly and disassembly of the third latching part 51 and the third latching groove 2112 are simple and easy for users to operate. Alternatively, the side panel 5, which is detachably connected to the support structure, may also have a third latching groove 2112, and the connecting section 211 may have a third latching part 51 that can engage with the third latching part 51. The number of third latching parts 51 can be one, two, three, four or more, with multiple third latching parts 51 arranged at intervals along the length of the connecting section 211. Third latching slots 2112 are arranged in a one-to-one correspondence with the third latching parts 51 to ensure the stability and reliability of the side plate 5 in its unfolded state. Of course, in other embodiments, the third latching parts 51 and the third latching slots 2112 can also be elastic buckles or other latching structures; this embodiment of the present invention does not impose specific limitations here.
[0072] like Figure 9 As shown, the crossbeam 21 further includes a third limiting part 213 located on the side of the connecting section 211 away from the supporting section 212. When the third engaging part 51 engages with the third engaging groove 2112, the third limiting part 213 contacts the side plate 5. The contact between the third limiting part 213 and the side plate 5 means that they may abut each other or there may be no interaction force. Thus, when the third limiting part 213 contacts the side plate 5, it can restrict the side plate 5 from continuing to rotate relative to the crossbeam 21 toward the third limiting part 213, thereby providing a clear limit and guidance for the rotation of the side plate 5. Furthermore, when the third limiting part 213 abuts against the side plate 5, it can also improve the stability of the side plate 5 in the unfolded state and reduce the possibility of accidental folding of the side plate 5. Simultaneously, the crossbeam 21 located on the rear side can also be provided with a third limiting part 213 to limit the rear plate 4. The specific limiting method is the same as that of the side plate 5, and will not be described in detail here.
[0073] like Figure 10 As shown, when two adjacent folding units 10 along the width direction share a crossbeam 21, the crossbeam 21 includes two support sections 212 arranged opposite to each other on both sides of the connecting section 211. The shelves 1 of the two folding units 10 are respectively mounted on the two support sections 212. In this way, the versatility and standardization of the crossbeam 21 can be improved, the number of molds and production costs can be reduced, and the production and assembly process can be simplified.
[0074] like Figure 2 As shown, in one embodiment, the folding member 31 rotates inward relative to the supporting structure. Thus, in the folded state, the folding assembly 3 is located between the two supporting structures, for example, housed within a receiving cavity, thereby reducing the overall depth dimension of the folding cabinet for easier handling and storage. This also protects the folding assembly 3 from outward protrusion, preventing bumps or damage. Of course, in other embodiments, the folding member 31 may also rotate outward relative to the supporting structure to reduce the overall thickness of the folding cabinet.
[0075] like Figures 13 to 16 As shown, in one embodiment, the folding assembly 3 further includes a connecting joint 32, with the ends of both folding pieces 31 furthest from the supporting structure rotatably connected to the connecting joint 32. Connecting the two folding pieces 31 via an independent connecting joint 32 improves the strength of the joint point, thereby enhancing the strength and durability of the folding assembly 3. Furthermore, the connecting joint 32 can serve as a standardized part, facilitating production and replacement, and increasing the modularity of the folding cabinet. Of course, in other embodiments, the two folding pieces 31 can also be connected via hinges, other structures, or other means, as long as a rotatable connection can be achieved. This embodiment of the present invention does not impose specific limitations.
[0076] like Figures 15 to 16 As shown, in one embodiment, the connecting joint 32 includes two interconnected third rotating parts 321. The ends of the two folding pieces 31 furthest from the first rotating part 224 are respectively rotatably connected to the two third rotating parts 321. Specifically, the third rotating part 321 is provided with a third shaft hole 3212, and the end of the folding piece 31 connected to the third rotating part 321 is also provided with a second shaft hole 312. The third rotating part 321 and the folding piece 31 are rotatably connected at the third shaft hole 3212 and the second shaft hole 312 via a first rotating shaft (not shown). This effectively prevents the folding piece 31 from shaking or jamming during rotation, ensuring the stability of the folding cabinet during folding and unfolding. It also prevents the folding piece 31 from sliding along its width, improving the overall strength and stability of the folding cabinet. Furthermore, the fact that the two folding pieces 31 rotate relative to the connecting joint 32 around two mutually parallel rotating axes also prevents interference between the two folding pieces 31 during folding. Of course, in other embodiments, one of the third rotating part 321 and the folding member 31 may be provided with a shaft hole, and the other may be provided with a rotating shaft; or, the third rotating part 321 and the folding member 31 may be connected by other structures such as hinges or joints, as long as the two can be rotated and connected. This utility model embodiment does not impose specific limitations here.
[0077] like Figures 15 to 16As shown, the third rotating part 321 includes a second engaging part 3211, and the folding member 31 can be detachably engaged with the second engaging part 3211. Specifically, the end of the folding member 31 connected to the third rotating part 321 is also provided with a first slot 313 that can engage with the second engaging part 3211. In the unfolded state, the second engaging part 3211 engages with the first slot 313 to ensure the stability and reliability of the folding assembly 3 in the unfolded state, prevent the folding member 31 from accidentally rotating and folding relative to the connecting joint 32, and reduce the shaking of the folding cabinet during use. In the folded state, the second engaging part 3211 separates from the first slot 313 to avoid affecting the normal rotation of the folding member 31. Furthermore, the assembly and disassembly of the second engaging part 3211 and the first slot 313 are simple and easy for users to operate.
[0078] like Figures 15 to 16 As shown, the third rotating part 321 also includes a second limiting part 322. When the folding member 31 engages with the second engaging part 3211, the folding member 31 contacts the second limiting part 322. Contact between the folding member 31 and the second limiting part 322 means that they may abut each other, or there may be no interaction force. Thus, when the second limiting part 322 contacts the folding member 31, it can restrict the folding member 31 from continuing to rotate relative to the connecting joint 32 toward the second limiting part 322, thereby providing a clear limit and guidance for the rotation of the folding member 31. Furthermore, when the second limiting part 322 abuts against the folding member 31, it can also improve the stability of the folding member 31 in the unfolded state and reduce the possibility of accidental folding.
[0079] like Figure 13 , Figure 15 and Figure 17 As shown, in one embodiment, one of the back panel 4 and the folding component 31 is provided with a first insertion part 41, and the other is provided with a first slot 311 that can be inserted and engaged with the first insertion part 41. Thus, the connection between the back panel 4 and the folding component 31 is simple, allowing for quick assembly and disassembly without the need for external tools, facilitating user operation and improving the usability and convenience of the folding cabinet. Furthermore, users can choose whether to install the back panel 4 according to their actual needs. Of course, in other embodiments, the back panel 4 and the folding component 31 can also be detachably connected through snap-fit, interference fit, or detachable screws, bolts, or other fasteners, as long as the stability and reliability of both in the assembled state can be ensured. This embodiment of the present invention does not impose specific limitations here.
